Because of safety concerns regarding the proximity of the right-field wall to the east end zone, whichever team is on offense will head east.
The following is the Cubs' statement:
“The Chicago Cubs are surprised by the Big Ten's last-minute statement regarding changes for tomorrow's Northwestern-Illinois football game at Wrigley Field. Let there be no doubt: the safety of the student-athletes has been – and remains – the number one priority since the concept of this game was first discussed more than a year ago, and all parties have gone to complete lengths to ensure student-athlete safety for this contest.
“The essential item in our negotiations to host the football game at Wrigley Field was obtaining approval of both universities and the Big Ten for the field dimensions as related to player safety issues. The field dimension layout was delivered to the Big Ten approximately eight months ago and was approved by the conference. Last month, the field was built exactly to the dimensions previously approved by the Big Ten. Last week, a Big Ten official performed an on-site visit at Wrigley Field, participated in a field walk-thru and raised no issue with the field dimensions, painted lines and boundaries previously approved by the Big Ten.
“This game would not have been scheduled if it did not pass the strict and meticulous standards of everyone involved, a process that began more than a year ago. All are in agreement Wrigley Field is a safe venue to host a football game. Other baseball parks, including tomorrow night's game in Yankee Stadium, feature similar football field-to-venue grid dimensions and rule changes are not considered for football games played in other baseball parks.
“We have reached out to the Big Ten to further discuss the playing field. While we are surprised by this morning's last-minute statement, all agree that tomorrow will be an historic event and a wonderful experience for the fans, the schools and the student-athletes.”
